Olea europaea L. (Olive) plant has been used by humans for many years for the treatment of diseases. The aim of this study was to investigate the total phenolic compound and antioxidant activities of methanol extract of the leaves of Olea europaea L. (Olive) plant. Total phenolic content of Olea europaea L. (Olive) plant leaves was determined by a method using Folin Ciocalteu reagent. Antioxidant activities were determined by DPPH (1,1-diphenyl-2-picrylhydrazil) and FRAP (Iron ion reducing antioxidant power) methods. Different concentrations of reference samples between 1-100 μg/mL were prepared to determine the equivalent antioxidant capacity of the extract. The phenolic compound of methanol extract of the leaves of the Olea europaea L. (Olive) plant was the highest at a concentration of 1000 μl/ml. DPPH radical scavenging capacity (inhibition %) values were found to be significantly higher in the extract at 1000 μl/ml than the extracts at other concentrations. This study supports the potential use of Olea europaea L. (Olive)in folk medicine.
